What to know

  • Researchers found a previously unidentified 'climate teleconnection': abnormal Tibetan Plateau warmth in early winter preceded record California-region rainstorms by about a month, in 2016-17 and 2022-23.
  • The events caused roughly $6.6 billion in damage and killed at least nine people, occurring during La Niña years when dry conditions were expected.
  • Current forecast systems rely heavily on ocean conditions like El Niño and failed to predict the extreme rainfall, per the study's lead author.
  • Researchers say the finding could improve early warnings for West Coast communities and reduce property damage and loss of life.

    SCMP covers the study for a China-focused audience

    The South China Morning Post reports on the UCLA-led study, noting the record rain occurred during La Niña years when drier conditions were expected, complicating existing forecast models.

      Atmospheric scientists have discovered that unusual warming in the Tibetan Plateau of the Himalayas in early winter sets off a chain reaction across the Northern Hemisphere, eventually strengthening storms that drench California. https:// theconversation.com/how-heat-o…

    Study's lead author explains mechanism in first-person account

    Yongkang Xue, writing for The Conversation, describes how early-winter heat on the Tibetan Plateau triggers a chain reaction across the Northern Hemisphere that strengthens the jet stream and storms reaching California, and argues the results could improve forecasts.

    Study identifies Tibet-California climate teleconnection

    Live Science reports on a new study finding that abnormally high temperatures on the Tibetan Plateau in December 2016 and February 2023 preceded record-breaking rainfall in California, Nevada, Oregon, Utah and Arizona about a month later, causing roughly $6.6 billion in damage and at least nine deaths.

    “This study provides the first evidence from observational data analysis and model simulations that abnormally high early-winter temperatures on the Tibetan Plateau led to stronger atmospheric rivers along the U.S. Pacific Coast, driving heavy regional precipitation…”
